FALSE BOTTOM ron WAsHTUBs im THELIKE;

To all whom t may concern e Be it knownthat I, RUDon1 i-rl ILorr, asubject ot theGerinan Empire, residing at i Tliermopolis, in the countyof` Hot Springs and State of l/Vyoming, have invented certain new anduseful Improvements inFalse Bottoms for VVashtubs and the like,` ofwhich the following is a specilication.

`The present `invention relates `to a false bottom for washtubs and thelike, and has `for its object to provide a device of this characterwhich embodies novel features `olf construction whereby an effectivefrictional contact with the` clothes is obtained and also whereby thewater may be heated under the false bottom so as to maintain the same atpresent instance the false bottom is shown y the proper temperature. g,A further object of the invention is to provide a falsev bottom forwashtubs which is not only constructed to remove the dirt fromthefclothes by friction, but also Vto strainthe dirt from the upper partofthe Wash tub orvessel tothebottom thereof so as to keep the waterand`suds in said upper part of the tub in a clean condition.`

`With these and other objects in view, the

invention consists in certain novelcombina-` tions and arrangements "ofthe parts as will more fully appear as `the description proceeds, thenovel features thereof; being pointed out in the appendedclaims. y y

For a full understanding of the finven-` tion, reference is to be had"to the following description and accompanying drawings, in Q which zy yy Figure l isa plan view of a false bottom constructed in accordancewith the invention, showing the same as arranged within an ordinary washtub. Fig. 2 is a transverse sectional view on the line 2-2 oi Fig. l.Figf is a sectional view on the line 3-3 oi Fig. 1, and Fig. @L is atransverse sectional view through a modified form of the i1ivention,showing the same as "fitted within an ordinary wash tub.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by the samereference characters.

Referring to the drawings, the reference character A designates thefalse bottom in its entirety, the said false `bottom being adapted to beremovably placed in a wash tub, washing machine or the like so asto restloosely upon the bottom thereof. In the v Specification of LettersPatent.

for the purpose of illustration as iitted within a wash tubl.`Thebottoln A, as shown by Figs. l` and 2, is preferably made in twosubstantially semicircular sections 2 2 which are loosely connected `insome suitable manner as by means of the hinged links `Esolasto-bereadily folded upon each other when it is `desired tocollapse'the false bottom. asliing machines are frequently made with acontracted top, although where the Afalse l bottom is constructed in twohinged sections,

as above indicated, no difficulty is encoun` tered in placing the samein position within thefinterior of thewashingmachine. l.

The false bottom A may be made from sheet metal or` heavy glass, theadjacent l edges of the twolsections Qf-Qithereof being looselyconnected by the link members 3. Inl the present instance the'extremities of the `link members 3 are rolled to provide small sleeveswhich receive the rods or wires `3, the said wires or rods beingsimilarly en `gaged at intermediate points between the links bycorresponding sleeve members 3b upon the sections 2.# `This constructionadmits of the two sections 2-4-2 being readily folded when such becomesdesirable.

Each of the sections 2 of `the `falsebottom is `provided with aplurality of independent sets of` corrugations runninglat" angles to soY each othei. In the present instance each half 2 of the false bottom isdivided into two segmental sections each oi. which is provided with aset of corrugations 4, the cor-` `rugations of each set being parallelto each other and to the radius passing through the middle of thesegmental section. It will thus be obviousthat the various sets ofcorrugations 4 extend in different directions so that the clothes willbe effectively acted upon to remove the dirt therefrom, regardless ofthe direction in which they are moved over the bottom. Each set of thecorrugations is pro vided with the longitudinal slots 4 in the valleysor depressions betweenthe independent corrugations, and with the"perforations 4b which `extend in series along the ridges or raisedportions of thecorrugations. Provision is thus made for carrying thedirt under the bottom as quicklyfas it is loosened bottom of the tub. Awater space is thus' 4a and perforations 4b and thus be carried awa fromthe clothes.

T e invention also contemplates the `prov vision of means forheating'the water to maintain the same at the ture. For this purpose aveating coil 7 1s arranged under and carried by the false `bottom A, thesaid heating coil being secured to the false bottoml by suitable clips8, and maintained out of electrical contact therewith by the insulation9. The terminals 10 of the heating coil 7 extend to a suitable plug 11,and electric current may be su pliedto the heating coil from anysuitable source.

As indicated by Fig. 2, the heating coil 7 is formed in complementalsections which are rigidly and permanently applied to the sections 2 2of the bottom, the adjacent ends of the complemental sections beingconnected by coiled portions 7a of insulated wire. These coiled portions7 a are adapted to be elongated when the false bottom `is `collapsed andcontracted when the false bottom is extended or inverted for use. Provi#sion is thus made for the folding of the false bottom A,`although theoperative sections of the heating coil 7 are maintained in a spacedpositionv from the false bottom and out of electrical contact therewith.

A modification isv shown by Fig. 4, in which the false bottom A isconstructed in one integral section, and is provided at the peripherythereof with `the upwardly pro jecting flange or sides 12. This flange12 may be ofany desired height, and is formed with several sets ofcorrugations 13, corre-1k roper temperafY i sponding tothe sets ofcorrugations 4 of the bottom, and extending at different angles to eachother. As the clothes are agitated and broughttinto contact with thecorrugations 13 of the side flanges 12, the said corrugations 13 willcoperate with the corrugations 4 of the bottom to act frictionally uponthe clothesA and remove the dirt therefrom.

Having thus described the invention, what l claim as new and desire tosecure by Letters Patent, is

1. A false bottom for' wash tubs and the like, including a removablebottom platesubdivided into segmental sectionswhich radiate from acommon center, each section being formed with' an independent set `ofparallel corrugations which are disposed at an angle to thecorrugationsfof adjacent seg-1 c through the middle of thesegmentalsection,`

slots being formed in the valleys ofthe corrugations which `extendsubstantially the full length thereof, while the crowns ofthecorrugations are each provided with a series of perforaticns. f y

In testimony whereof I aix my signature in presence of two witnesses. Vi
